I actually hoped this to be the same type as [Shitsuji Shoujo to Ojou-sama](www.mangaupdates.com/series.html?id=44449) but turned out to be something generic straight. I mean, an S princess, a reverse trap and a gynophobic (is it even the right term?) boy. Riiiiight.
Well, not too bad overall with good amount of well-placed fanservices here and there. I mean, lots of em. Turning off brain is necessary for this kind of series.
Also, [first episode and someone is dying already and most likely on his way to become an M](http://kurogane.animeblogger.net/2011/07/08/mayo-chiki-01/).
